The point of the first one is that you can create snapshots from within the product where profiling data isn't forever. This is so you can use the pprof.me link in a GitHub issue, PR, or elsewhere and trust that the data never goes away even if the original data went out of retention. We actually originally built pprof.me out of frustration that users of Prometheus (several of us are Prometheus maintainers) at best submitted screenshots of profiling data when all we wanted was an easy way to explore it.

I agree that neither of these are terribly complicated features, but as far as I know no other product on the market actually has this combination. (yes, you can export data from most systems and use a different visualization tool but the point of products is to provide a single integrated package)
